Can I display multiple maps (shortcodes or widgets) on one page?

this feature is not yet available

Can I display multiple map markers?

Currently only 1 marker can be used on a non-route map

how do I change the color and size of the 'get directions' button?

the button is totally styled in CSS so you can change this as you like in your theme's style.css

can I change the style of the map pointer?

for the route pointers (A to B) the style is fixed, but for the single map pin you can change these. There is a filter hook that can be coded in your theme's functions.php
= My operating radius circle isn't a circle?
This happens sometimes when your zoom level is too high for your radius crcle to fite, try a different zoom level to get your circle inside the map
